Data Profiling,is does not mean knowing every morsel of data in every table, it can and should mean having a high-level view of what is (and equally important—what is not) in a column of data. This knowledge can often be a valuable first step in deciding on the validity of a data source, and even in choosing wheth折磨 发表于 2025-3-27 01:12:57

Yet this basic scenario will inevitably not match everybody’s requirements all of the time. When developing ETL solMusket 发表于 2025-3-27 05:39:18
ETL Process Acceleration, all available processor cores and attempt to parallelize the load, you could shorten load times—as we saw in Chapter 13 . Yet here are other aspects of ETL loads that also need to be taken into consideration if you are trying to optimize a load and ensure that the entire time taken by a job (and noAlbumin 发表于 2025-3-27 12:57:14
